Specification of Letters Patent..

Patented April 9, 1907.

Application filed March 24,1906. Serial No. 307,848-

Tb all whom it may concern: r

Be it known that I, GEORGE N. HINCI-I- MAN, a citizn of the United States, residing at Webster Groves, in the county of St.

Louis and State of Missouri, have invented a certain new and useful Adding-Machine, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invcr. ion relates to adding-machines, and more partii'mlarly to that class of addingmachines described in my prior patents, Nos. 833,388 and 833,389, both of October 16,1906.

The object of my invention is to provide the machine with a pa er su port or platen of any desired len th, a ong which the adding and printing mefiianism may be moved to cooperate therewith to print the numbers in various columns. I accomplish this result by providing a base with a track or otherguide upon which the adding and printing mechanism is adapted to move and carrying upon said base a printing roller or platen for supporting the paper, so that the adding and printing mechanism may be moved longitudinally of said platen, and also by changing the position the printing mechanism, so that 1t may properly cooperate with said platen.

In the accompanying drawings, which illustrate one form --of machine made in ac- -cordance with my invention, Figure 1 is a side view of the complete machine. a top plan view, a portion of the casing of the adding and printing mechanism bein r in section. Fig. 3 is a to plan view of t 1e base and mechanism for ocking the adding and printing mechanism to the base. Fig. 4 is an enlarged side elevation of a portion of the frame of ti: e adding and printing mechanism, togell er with the parts carried thereby, the case being shown in sect ion. Fig. 5 is a central section through the complete machine. Fig. 6 is an enlarged view of some of the mec anism shown in Fig. 5. Fig. 7 is an enlarged "iew showing the mechanism for operat ing the printing roll or platen. Fig. 8 is a section showing a detail view of the mechanism for locking the adding and printing on the line 9 9 of Fig. 6. Fig. 10 is a section on the line 1010 of Fig. 6. Figs. 11, 12, and 13 are diagrammatic views showing the movements of the various gears in the machine, and Fig. 14 is a top plan view of the mechanism for controlling the printing-roll shown in Fi .7.

Like mar s of reference refer to similar parts in the several views of the drawings.

represents the base, upon which is a longitudinally-extending track 21. At the rear end of the base 20 are uprights 22 for supporting the printing roll or platen 23 and operating parts therefor, as wlll be hereinter more fully described.

25 is the casing of theadding and printing mechanism. This casin 25 is rovided with grooved wheels or r0 lers 26, w rich run upon the track 21.

Arranged on the base 20 between the rails of the track 21 are two perforated bars 27, which cooperate with detents 28 one sliding bar 29, carried on the bottom of the casing 25. A spring 30'is secured at one end to a pin 31, carried on the bar 29, and at the otherto a pin 32, rigidly secured to the bottom of the casing 25. .Pivoted to the casing 25 at 34 is a lever 35, Fig. 3, projecting at the side of the casin 25 and provided with a handle 36. This lever 35 is connected to the bar 29 by a slot-and-pin connection 37, so

that the bar 29 may be moved lon itudinally to disengage the detents 28 from t e perfora tion 33, 1n the bars 27, and thus release the adding and rinting mechanism. Fig. 2 is Oontaine within the casing 25 is the adding mechanism, the principal part of which is the same as in my two prior patents hereinbefore referred to, and it will therefore be only briefly described.

are the numeral-keys, and 41 the orderkeys, by means of which the adding mechanism is operated. The order-keys 41 position the carriage 42, Fig. 5, and the numeral-keys -40 govern the transmission of motion from the motor 43 to the laterally-moving gear 44, the lateral movement of which is controlled by the carriage and which transmits rotary movement to the adding mechanism. This laterally-moving gear 44 is adapted to mesh with a set of gears 45, loosely mounted on a shaft 46, which gears in turn mesh wit h gears mechanism to the base. Fig. 9 is a section 4.7, loosely mounted on a shaft 48. 'lhese ICC gears 47 correspond to the gears to which the printing-wheels are attached in my prior patents. In the present instance, iowever, they are not provided with printing- Wheels.

The gears 45 also mesh with idle adapted to be brought into mesh with repeat-gears 51 for repeating the number, as described in my prior patent, No. 833,389. The shaft 46, above referred to, is provided with a comb 52, cooperating with a pin 53 on the wheels 45 to return said wheels to zero.

54 is carrying mechanism cooperating with the adding-wheels 50.

The operation of the parts above referred to will be now briefly described.

One of the order-keys 41 is first depressed, so as to move the carriage 42 the roper num ber of spaces toward the left am so position the sliding gear 44 in the proper order to begin the registration of 'a number. The numeral-keys are now depressed, and the motor 43 causes the gear 44 to rotate, and thus set up the number in the gears 45 and 47. The adding-gears 56, however, are out of engagement with the gears 49, and the gears 47 are also out of engagement with the train of gears, hereinafter to be described, which operate the printing mechanism. Upon the operation of the keys, therefore, the number is simply set up in the gears 45 and 47 and is neither printed nor accumulated in the adding mechanism. When the handle is pulled, however, the adding-wheels 56 are brought into engagement with wheels 49, so that the return of the wheels 45 and 47 causes the number to be accumulated in the adding mechanism, and at the same time it is transferred to the printing mechanism by means which will be hereinafter described.

Adjacent to the gears 47 are a set of gears 55, loosely mounted upon a shaft 56. These gears are normally out of mesh with the gears 47, but are adapted to be moved laterally, so as to mesh therewith. ltigidly secured to the shaft 56 is a wide gear 57, Figs. 9 and 10, which meshes with a gear 58, loosely mounted upon the shaft 48 with the gears 47, and this gear 58 in turn meshes with a gear 59, rigidly secured to the shaft 46, which is operated by the pull of the handle 60, Fig. 2. The object of this train of gears 57, 56, and 59 is to rotate the shaft 56, which carries a comb 61, ada )ted to engage with pins 62, carried in the wheels 55. The gears 55 in turn mesh with wide gears 63, loosely mounted upon a shaft 64. These gears 63 are provided with pins 65, ada )ted to contact with a fixed comb 66, carrie in plates 67, which also serve to carry the shafts 56 and 64.

68 are half-gears loosely mounted upon a shaft 69 and each having secured to it a large gear 76, meshing with a rack 71, carrying a printing-bar 72, in which are niovabl y mounted type 73. In order to transfer the movement from the gears 63 to the half-gears 68,

1 mount in the plates 67 four shafts 75, upon.

into contact with the printing-roll 23 by hammers 77. Each of the hammers 77 is pivoted at its forward end to one end of a link 78, the opposite end of which is loosely mounted upon the shaft 69, and at the other to a link 79, pivoted on a shaft 86, carried in the plates 67. Each of the links 79 is provided with a rearward and downward projection 81, carrying a pin 82. Each of the pins 82 is adapted to be engaged by means of a hook 823 on the end of a lever 84. The levers 84 are pivoted on a shaft 65, carried by links 86, pivoted at 67 to the plates 67. The upper ends of the levers 64 are guided by a comb 88, carried by a pair of levers 89, pivoted on the shaft 85 and also on a shaft 90, carried by links 91, rigidly secured to a rockshaft 9'2, journaled in the plates 67. (arried by the levers 69 is a shaft 93, on which are pivoted detents 94, adapted to engage )ins on the levers 64. These levers 94 are field in position against the stop 96 by means of springs 97, each secured at one end to an extension of the lever 94 and at the other to a rod 98, carried in the levers S9. Pivoted on a shaft 166 are levers 161, each having a lip 162, adapted to be engaged by a comb 163 in the printingslide 164. Pivoted to the upper end 'of each of the levers 161 is a slotted link 165, guided by a shaft 166 and bearing against the lower ends of the levers 84. It is evident that when the printing-slide 104 is positioned by the order-key and operated by the pull of the handle it will move all of the levers 161 correspomling to the orders in which characters are to be printed, and consequently the links 165 of the corresponding orders will operate the levers 84, so as to cause the detents 64 to take over the pins 95, and thus lock these levers in position, so that their links RI will take over-the pins 82 of the corresponding printing-hammers, so that when the levers H4 and 69 are moved down ward, as will be hereinafter described, the ninting-ha-nnners 77 in the proper orders will be actuated. A stop 167 is arranged in the path of the detents 94, so as to release the said detents at the proper time, and thus release the printing-llammers to print.

168 are the springs for holdingthe links 79 in their proper position, and 169 the springs for holding the levers 84 in the proper position with relation to the levers 89. The levers 161 are held in normal position by springs 116, secured at one end to the said levers and at the other to a rod 111, carried in the plates 67.

112 is a spring normally hold ng the shaft 56 to the right.

115, Fig. 4, is the handle-shaft operated by the handle 60, hereinbeforereferred to. Secured to this shaft 1 15 is an arm 116, to which is pivoted a link 117. This link 117 is pivoted at the opposite end to a sector 118, loosely mounted on the shaft 92 outside of the plate 67. (See also Fig. 9.) The sector 118 is provided with a pin 119, which passes through a segmental slot 120 ina second sector 121, arran ed between the sector 118 and a plate 122, s idingly mounted on the plate 67. The said second sector 121 is rigidly secured to the shaft 92. The pin 119 also passes through a vertical slot 123 in the sliding plate 122. Pivotally mounted on the sliding plate 122 is a bar 124, having a beveled forward end 125, which is adapted to engage with a beveled face 126 on a camblock 127, rigidly mounted on the shaft 56. The bar 124 is normally held in position a ainst a stop 128 by a spring 129. The p ate 122 is provided with an upward and rearward extension 130, upon which is yieldingly mounted a plate 131, having a down ward extension 132, adapted to come in contact with a pin 133 on an arm 134. This arm 134 is rigidly secured to a shaft 135, (see also Fig. 6,) 'ournaled in the plates 67. Rigidly secure to the shaft 135 inside ;of the plate 67 are a pair of arms 136, carrying a centering-pawl 137, adapted to be brought into engagement with the wheels 70, so as to center them, and thus preserve the alinement' The centering-pawl 137 is of the type 73. held in its normal position by means of a spring 138.

It will be evident that when the handleshaft is rotated its movement will be communicated, through the arm 116 and link 117, to the sector 118. The first effect of this movement will be to swing the sector 118 on the shaft 92 upon which it is loosely mounted. The pin 119, however, extending through the slot into the slot 123, will, because of its engagement with the edge of said slot 123, move the plate 122 toward the rear. As soon as the beveled edge of the bar 124 comes in contact with the beveled edge 126 on the cam-block 127 the shaft 56 will be rotated so as to bring the pins 62 in the wheels 55 firmly against the comb 6]., so as to aline -properly position the roll 23.

her will be transferred, through the gears 55, 65, 76, and 68, to the gears 70, which control the printin -bars 72. After the printing-bars are positioned the downwardlyprojecting detent 132 will come into contact with the pin 133, and thus throw the centering-pawl 137 into engagement with the wheels 70 to aline the type. After this the pin 119 will come in contact with the end of the slot 120 in the sector 121 and move the said sector. This sector being rigidly secured to the shaft 92 will rotate the same and through the links 91 swing the levers 89 downward, so as to operate the hammers 77 in the manner hereinbefore described.

The uprights 22,carried on the base 20, as

hereinbefore described, have journaled in their upper ends the printing-roll 23, Figs. 1, 2, 5, and 7. The shaft of this printing-roll 23 is provided at its ends with milled heads 145, by means of which the roll may be manually rotated. The right-hand end of this shaft is also provided with a ratchet-wheel 146 and a star-wheel 147. The uprights 22 are also rovided with shafts 148, 149, 150, and [151.

he shaft 148 supports a paper-guide 152, which terminates adjacent to the paper-roll 23. Loosely mounted on the shaft 150 is an arm 1 53 ,which bears against a centering-pawl 154, which engages with the star-wheel 147 to The pawl 154 is pivoted to the frame 22 at 163, Fig. 2. The arm 153 is held in position by a spring 155, Fig. 7, secured at one end to the said arm and at the other to the upright 22. A pin 142 on the shaft 150 engaes a pin 143 on the arm 153 for releasing t e pawl 154. The shaft 150 also has loosely mounted on it an apron 156 for holding the paper in contact with the roll 23. The apron 156 is held against the roll 23 by means of springs 157, carried on arms 158, loosely mounted on the shaft 151. The arms 158als0 carry feed-rolls 159, which assist the apron 156 in holding the paper against the roll 23. The shaft 150 is also provided with a cam-blade 160, bearing on the top of the arms 158, and at the left-hand end with a thumb-piece 161, by means of which the shaft may be rotated to throw the detent 154 out of engagement with the starwheel 147 and also to throw the apron 156 and feed-rolls 159 out of engagmnent with the roll 23. The arms 158 are held in their normal position by meansof a spring 1 62, secured at one end to one of the said arms and at the other to the paper-guide 1 52. Loosely mounted on the shaft 148 are apair of arms 165,

, united at their lower endsby a shaft 166, the

said arms and shaft together forming a feederadle. Pivoted to the right-hand arm. is a feed-pawl 167, the end of which engages with the teeth on the ratchet-wheel 146. The feed-pawl 167 is adapted to come in contact with a stop-piece 168, secured t0 the righthand arm 165. This stop-piece 168 is provided with three faces 169, so that three different feeds may be obtained by moving the said stop-piece 168. The feed-pawl 167 is held in its normal position by means of a spring 170, and the shaft 149 is provided with a finger-piece 171, having a cam projection 172 for throwing the feed-pawl 167 out of engagement with the ratchet-wheel 146. The shaft 166, carried by the arms 165, slides in a hub 174 on the end of a link 175.. This link 175 extends through a slot 176 in the center of the rear end of the casing 25,and its inner end is hooked over a rod 17 7, Fig. 5, carried by arms 178, rigidly secured to a shaft 179, journaled at the upper end and rear end of the machine-frame within the casing 75. This shaft 179 has projecting downwardly at its right-hand end an arm 180. This arm 180 has pivoted to its lower end a link 181, provided with a curved slot 182, having an upward extension 183, as shown in Fig. 7. Projecting through the upward extension 183 of the slot 182 is a pin 184, carried in the end of an arm 185, rigidly secured to a shaft 186, which is operated upon the pull of the handle 60. This arm 185 is also rovided with a cam-face 187 for purposes ereinafter to be described. The shaft 186 also has loosely mounted upon it a toothed sector 188. This sector 188 is provided with a pin 189, engaging a slot in the'error-key'bar 190. Loosely mounted on the shaft 186, adjacent to the arm 185, is a sector 191. This sector 191 is provided with three pins 192, 193, and 194.

he pin 192 projects below the toothed sector 188. The pm 193 engages the lower edge of thelever181, and the pin 94 engages the upper edge of said lever. The sector 191 is also providedwith a tooth 195, adapted to be engaged by a detent 196, pivoted to the machine-frame at 197. The detent 96 is also provided with a pin 198, adapted to be engaged by the cam 187 on the arm 185. The detent 196 is held in its normal position by means of a spring 199, secured at one end to the said detent and at the other to the sector 191.

The inking-ribbon 205 is actuated by ribbon-spools 206 in the ordinary manner. Passing from the ribbon-spools 206 the ribbon passes over small guide-wheels 207 and large guide-wheels 208. From the large guide-wheels 208 the ribbon passes over a ribbon-guard 209 between the type 73 and the paper-roll 23. If it isdesired to use narrow paper, a roll 210 of the same may be Wound on a shaft 211, carried in a support 212, arranged between the uprights 22.

In the ordinary operation of the machine when the handle is pulled forward the shaft 186 is rotated, and consequently the arm 185 is moved, the said arm is rigid upon said shaft. This causes the pin 184, which is in engagement with the upward extension 183 of the wheel 182, to force the link 181 backward, the pins 193 and 194 acting as guides for said link. The movement of the link 181 is communicated by the arm 180 to the shaft 179 which thus swings the cradle formed of the arms 178 and rod 177. As the link 176 is in engagement with the rod 177, the said link is moved toward the rear, thus swinging the cradle formed of the arms 165 and rod 166. This moves the feed-pawl 167 to the rear, the end of the pawl following the outline of the teeth on the ratchet-wheel 146 until the said pawl comes in contact with the stop 168, after which its movement toward the lever 165 will be arrested, and consequently its forward end will be swung downward and backward away from the wheel 146. According to the position of the stop 167 the pawl will follow the outline of one, two, or three teeth'. Upon the return of the handle the parts will a ain resume their normal position, and the eed-pawl 167 will engage with the wheel 146, and thus feed it through one, two, or three teeth, according to the position of the stop 168. When the error-key 190 is operated, the sector 188 will be swung upon the shaft 186 and owing to its engagement with the pin 192 will operate the sector 191. The pin 193 will follow the curve on the lower edge of the bar 181 until it strikes a straight portion of said portion, when it will raise the said bar, so as to move the pin 184 out of the upward extension 183 into the main or'curved part of the slot 182. At the same time the detent 196 will en age with the tooth 195 on the sector 191 and lock the sector in this position, so that it will remain after the return of the sector 188. When the handle is now drawn forward and the arm 185 operated, the pin 184 will move in the curved part of the slot 182 without movin the link 181, and consequently the paper-feed mechanism will not be operated. Upon the completion of the stroke the cam 187 on the arm 185 will strike the pin 198, and thus release the sector 191, so that it may return to its normal position. By moving the finger-piece 171 the feed-pawl 167 maybe moved out of engagement with the, ratchet-wheel 164, so as to prevent the feeding of the paper at any time. The apron 156 and feed-roll 159 can also be moved out of engagement with the roll 23 at any time by the movement of the finger-piece 161.

The operation of my machine is as follows: The numbers are written into the machine in the usual manner by means of the numeralkeys 40 after the carriage has first been positioned by means of the order-keys 41. The positioning of the carriage also positions the printing slide 104 in the usual manner. When the number is written into the machine by means of the numeral-keys 40, the laterally-moving ear 44 communicates the movement of the eys through the wheels 46 to the wheels 48. These wheels 48, however,

|are out of engagement with the wheels so that the wheels 55 6576, &c., are not operated when the number is written into the machine. Upon the pull of the handle the gage with the teeth 102 of the pawls 101 in all the orders in which rinting is to take lace,

and thus cause the inks 105 to move t e le-- vers 84, so that their pins 95 are engaged by the detents 94, and consequently their hooks 83 locked in position to enga e with the pins 82 on the printing-hammer evers 79. The first movement of the link 117 causes the sector 118 to be rotated on the shaft 92, and this movement is communicated through the pin 119 to the slidin plate 122, causing said late to slide toward the rear of the mac ine. When the cam-bar 124 on said plate comes in contact with the cam-block 127 on the shaft 56, the said block tends to rotate the shaft 56, and consequently the comb 61 in said shaft comes in contact with the pin 62 on the wheels 55, thus moving the ins 65 in the wheels 63 firmly against the ed comb 66, so as to aline the wheels, after which the action of the camieces 125 and 126 moves the shaft 56v to the l eft, thus causing the wheels 55 to engage with the wheels 48. The movement of the handle now rotates the shaft 46,

and consequently the wheels 45 of all the orders in which numbers have been written. This movement is communicated through the wheels 48 to the wheels 55 and thence through the wheels. 63 and 76, and the halfwheels 69 to the wheel 70, which operates the typebars 72, so that said type-bars are moved upward, as shown in the diagram in Fig. 12. At the same time the shaft 56.is rotated by means of the train of gears 57, 58, and 59, so that its comb 61 moves in the direction of the arrow in Fig. 6, said comb being followedb the pins 62 of all the orders in which num ers have been written. comb itself moves throu h a distance equal to ten-tenths of the whedl 65, while the pins 62 move a distance corresponding to' the value of the di 't written into the machine in the iven or er. After the type-bars 72 have een thus positioned the downward projection 132, Fig. 4, comes in contact with the in 133, and the centering-pawl 137 is thrown mto engagement with the teeth of the wheel 7 0, so as to properly center the type 7 3. During this transmission of the movement the pin 119 comes in contact with the end of the slot 120 in the sector 121 and moves the said sector, which being ri idly secured to the shaft 92 rocks the sad shaft, so as to draw the arms 89 downward. This causes the hooks 83 of all the levers 84 which. have been moved by the links 105 to engage the pins 82 of the corresponding hammers, and consequently to withdraw the hammers against the The tension of the spring 108. When the limit of the forward movement of the handle is reached, the detents 94 will come in contactwith the stop-bar 107, so as to release the levers 84, and consequently the hammers 77, so that the" hammers deliver a printingblow to the type, because of the tension of the springs 108. When the end of this forward strokeisreached, the cam 127 is moved in such a position that it can slide under the bar 124, so that the wheels55 move laterally out of engagement with the wheels 48. Upon the return of the handle the pins 62 of all the wheels 65 which have been rotated areengaged by the comb 61 on its return movement, and consequently the type-bars 72 are returned to their normal position, as shown diagrammatically in Fig. 13. Upon this return movement the cam-block '17 2 simply lifts the bar 124 against the pressure of the spring 129. The: operation in taking the total, subtotal, or repeatin a number is in all respects the same as w en writingin a number in so far as the present invention is concerned, and consequently no further description is necessary of these operations.

The operation of the paper-feeding device has been fully hereinbefore described.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
